Hector’s dolphin is an endemic coastal dolphin found mainly around the South Island. It is among the world’s smallest marine dolphins. It has bold grey, black and white markings, no obvious beak and a rounded black dorsal fin. Adults reach about 1.5 metres.
Populations occur along the South Island’s east, west and south coasts, usually in shallow water. Banks Peninsula is an important stronghold. Small groups feed on fish and squid using echolocation. They may approach boats but must not be pursued or crowded.
Hector’s dolphin is Nationally Vulnerable. Fishing mortality, toxoplasmosis and disturbance threaten its populations. Akaroa and Lyttelton harbours are leading locations. Curio Bay offers possible shore-based sightings.
